Solar Energy vs Electricity

One of the biggest challenges that solar energy has faced in the past is its cost. When looking at solar energy vs electricity, the costs of providing fossil fuel-based electricity to the average home has been much cheaper than providing electricity from solar energy. In 1977, when solar energy was first introduced to the US market as a possibility, the cost per watt of silicon PV cells was $76.00.

In 2015, the cost per watt had been reduced to just $0.30 per watt.

Although there is no real cost number that can prove or disprove parity within an electrical grid, we can take a look at the cost of energy consumption per kilowatt hour from different resources to determine how well solar energy is doing when compared to traditional forms of electricity.

The Average Cost Per Kilowatt Hour for Solar In the US: $0.12

For the average homeowner in the United States, the cost per kilowatt hour for electricity that is generated through solar energy is just $0.12 per kilowatt hour. This includes the installation and manufacturing costs for the solar panels and ongoing maintenance costs that may be faced.

On the surface, this seems to put solar energy at a cost that is much lower than traditional forms of electricity. In Connecticut, Alaska, and Hawaii, for example, the cost of residential electricity in 2015 was above $0.20 per kilowatt hour.

Yet in a state like Washington, the average price of electricity per kilowatt hour paid by residential customers was just $0.09 per kilowatt hour.

This shows that there is some potential for solar energy to be an investment that makes sense for some homeowners. In terms of grid parity, however, solar energy may still have some progress that needs to be made.

The Average Wholesale Cost of Electricity Per Kilowatt Hour: $0.04

The cost of electricity is much like a retail transaction. The electricity is created by a power generator, such as a power plant. Utilities purchase this electricity from the power generator and then sell it to customers that fit into three different tiers: industrial, commercial, and residential.

The wholesale price that utilities pay the power generators for electricity is about $0.04 per kilowatt hour. Some industrial customers may pay less than $0.07 per kilowatt hour for the electricity they use because of the amount they consume. In comparison, the average price of electricity per kilowatt hour for residential consumers is nearly double the industrial price.

This means profits are built into our utility system. Until solar energy can compete with the wholesale rates, it will always be considered an “alternative” form of energy.
